Why is iodine used for radiation?
When you take potassium iodide, your thyroid gland absorbs it. If you get the right amount at the right time, it will saturate your thyroid gland. This can help block any inhaled or ingested radioactive iodine from being absorbed by your thyroid. This lowers your risk for radiation damage to that gland.Mar 18, 2022

Natural hormones, such as estrogen and testosterone, help some tumors grow. To stop their growth, doctors sometimes prescribe hormone therapy to reduce the amount of hormones produced by the body in order to stop the growth of the cancer.
How do monoclonal antibodies kill cancer cells?
Monoclonal antibodies target certain cells in the body by attaching themselves to those molecules. This causes some cancer cells to die and makes other cells more likely to be killed by radiation and chemotherapy.
What is the difference between immunotherapy and biologic therapy?
The difference is that chemotherapy attacks the cancer directly and biologic therapy helps your immune system fight the disease better.

What is a positron emission tomography scan?
A positron emission tomography scan is an imaging study using a very small dose of a radioactive tracer attached to a sugar that is injected into the patient. Different tissues (including tumors) use the sugar at different rates, a characteristic that may be detected by the scanner to create an image of the body showing areas of tumor activity.

Why it's done. More than half of all people with cancer receive radiation therapy as part of their cancer treatment. Doctors use radiation therapy to treat just about every type of cancer. Radiation therapy is also useful in treating some noncancerous (benign) tumors.
How does radiation damage cells?
Radiation therapy damages cells by destroying the genetic material that controls how cells grow and divide. While both healthy and cancerous cells are damaged by radiation therapy, the goal of radiation therapy is to destroy as few normal, healthy cells as possible.
How long does radiation treatment last?
Expect each treatment session to last approximately 10 to 30 minutes. In some cases, a single treatment may be used to help relieve pain or other symptoms associated with more-advanced cancers. During a treatment session, you'll lie down in the position determined during your radiation simulation session.

How long does it take for cancer to respond to radiation?
In some cases, your cancer may respond to treatment right away. In other cases, it may take weeks or months for your cancer to respond.
What is the purpose of radiation treatment?
If a person's cancer has returned (recurred), radiation might be used to treat the cancer or to treat symptoms caused by advanced cancer. Whether radiation will be used after recurrence depends on many factors. For instance, if the cancer has come back in a part of the body that has already been treated with radiation, it might not be possible to give more radiation in the same place. It depends on the amount of radiation that was used before. In other instances, radiation might be used in the same area of the body or a different area. Some tumors do not respond as well to radiation, so radiation might not be used even if they recur.

How is radiation given?
Radiation therapy can be given in 3 ways: 1 External radiation (or external beam radiation): uses a machine that directs high-energy rays from outside the body into the tumor. It’s done during outpatient visits to a hospital or treatment center. It's usually given over many weeks and sometimes will be given twice a day for several weeks. A person receiving external radiation is not radioactive and does not have to follow special safety precautions at home. 2 Internal radiation: Internal radiation is also called brachytherapy. A radioactive source is put inside the body into or near the tumor. With some types of brachytherapy, radiation might be placed and left in the body to work. Sometimes it is placed in the body for a period of time and then removed. This is decided based on the type of cancer. Special safety precautions are needed for this type of radiation for a period of time. But it's important to know if the internal radiation is left in the body, after a while it eventually is no longer radioactive. 3 Systemic radiation: Radioactive drugs given by mouth or put into a vein are used to treat certain types of cancer. These drugs then travel throughout the body. You might have to follow special precautions at home for a period of time after these drugs are given.
How does cancer spread?
Cancer can spread from where it started to other body parts. Doctors often assume that a few cancer cells might already have spread even when they can’t be seen on imaging scans like CT scans or MRIs. In some cases, the area where the cancer most often spreads to may be treated with radiation to kill any cancer cells before they grow into tumors. For instance, people with certain kinds of lung cancer may get radiation to the head, even when there is no cancer known to be there, because their type of lung cancer often spreads to the brain. This is done to help prevent cancer from spreading to the head even before it can. Sometimes, radiation to prevent future cancer can be given at the same time that radiation is given to treat existing cancer, especially if the area the cancer might spread to is close to the tumor itself.
Can radiation therapy be used for cancer?
Most types of radiation therapy don’t reach all parts of the body, which means they’re not helpful in treating cancer that has spread to many places within the body. Still, radiation therapy can be used to treat many types of cancer either alone or in combination with other treatments. While it's important to remember each cancer ...
What is systemic radiation?
Systemic radiation: Radioactive drugs given by mouth or put into a vein are used to treat certain types of cancer. These drugs then travel throughout the body. You might have to follow special precautions at home for a period of time after these drugs are given.
Can radiation be used before surgery?
For other cancers, radiation may be used before surgery to shrink the tumor (this is called pre-operative therapy or neoadjuvant therapy ), or after surgery to help keep the cancer from coming back (called adjuvant therapy ). For certain cancers that can be cured either by radiation or by surgery, radiation may be the preferred treatment.
Overview
Why It's Done
- More than half of all people with cancer receive radiation therapy as part of their cancer treatment. Doctors use radiation therapy to treat just about every type of cancer. Radiation therapy is also useful in treating some noncancerous (benign) tumors.
Risks
- Radiation therapy side effects depend on which part of your body is being exposed to radiation and how much radiation is used. You may experience no side effects, or you may experience several. Most side effects are temporary, can be controlled and generally disappear over time once treatment has ended. Some side effects may develop later. For example, in rare circumsta…
How You Prepare
- Before you undergo external beam radiation therapy, your health care team guides you through a planning process to ensure that radiation reaches the precise spot in your body where it's needed. Planning typically includes: 1. Radiation simulation.During simulation, your radiation therapy team works with you to find a comfortable position for you during treatment. It's imperative that you li…
What You Can Expect
- External beam radiation therapy is usually conducted using a linear accelerator — a machine that directs high-energy beams of radiation into your body. As you lie on a table, the linear accelerator moves around you to deliver radiation from several angles. The linear accelerator can be adjusted for your particular situation so that it delivers the precise dose of radiation your doctor has order…
Results
- If you're receiving radiation to a tumor, your doctor may have you undergo periodic scans after your treatment to see how your cancer has responded to radiation therapy. In some cases, your cancer may respond to treatment right away. In other cases, it may take weeks or months for your cancer to respond. Some people aren't helped by radiation therapy.
